Application filed. December I To alt whom it may concern:

Be it known that I, EDWIN BALL S'rnursoft, a citizen of the United. tates, end a resident of the borough of Brooklyn, county of liings, city and State of New York, have invented certain new and useful improvements in Eyelet and the Like Setting Machines, of which. the following is a specification.

For the purpose of illustrating my present improvements, I have chosen an eyeleting machine and my invention is described in connection with such a machine, but it is to he understood that said improvements are not limited to eyeleting mitchines, but on the contrary are equally applicable to other mechi'n'es, such as riveting machines and so forth.

Briefly stated, some of the objects oi my improvements are an improved method or operzttively supporting the eyelet or rivet box; improved means of operating the rondwey for the washers relative to the setting devices, etc, also an improvement designed to take care of such emergencies as the accidental clogging of the washers in their I'()it(lway, or after said road-way has become lillcd.

Other features of improvement will appear from the annexed description and such fem tures as are novel will he set forth in the claims.

In the rlrewings which show one form of my herein im rovements applied to en eyeleting mec inc, Figure 1 is it side elevation of such it machine with the head cleveted; Fig. 2 is a fragmentary view of the same showing the head down with the eyclet-road and other parts in corresponding position; Fig. is afront elevation looking at the machine from the left of Fig. 1; Fig. 4 is a vipw partly in section and partly in top plan along the line l i in Fig. 1; Figs. 5, 6, 7, and 8 are fragmentary views of the eycletsetting arts of the machine from the reverse side to t at shown in Fig. 1. in those views, the operative parts are shown. in four successive stages from an initial position with the I head elevated to a final position, Fig. 8, in

which the eyelet has been set in the materiel. j

' Describing no w my improvements with special reference to the devices of the draw ings, 1 is the frame of the machine. Mount ed above in hearings on the frame is a shaft 2 carrying a. pulley 3, adopted to be belted to any suitable source of power.

Mounted on the shaft 2 is a. disk 4 having it Specification of Letter Patent.

Patented Dec. 22, 1908 i cem-proje ition 5. The disk has a crank-pin l 6. Uperetively connecting said crcnlcpin with the knuckle of a pair of toggle arms 7 is e connect-ingrool 8. per toggle arm has trunnions 60 which work in stationery hearings on the frame of the machine and that of the lower toggle-arin is pivot/ally connected with a plunger 9 best shown in Fig. This plunger has a vertical reciprocating motion and for this purpose is mounted between guides 10 on the machine frame. Secured to the plunger is a hollow set 11 within which is located a springpressed spindle 113. o attempt is made to illustrate the details of said spring construction. as this is an old feature and not Within my present invention. It being suflicient to state here that the construction is such that the spindle is held normally extended out of the hollow'set, but when pressed from below i is capable of telescoping into it.

i The spear point l3 projects from an anvil I 16, which latter is supported in a vertical l socket in a horizontal extension of the frame I of the machine. A screw 14- scrows into the l horizontal arm of the frame directly under I heath the anvil and by adjustment of said l screw the anvil and spenrpoint can be moved j into various positions of vertical adjustment. A set-screw 61 (Fig. 1) beers on the anvil and holds it rigid in its socket in its given posis j tion of adjustment.

screw 14 hold the letter rigid in any. of its ad, justed positions. I p l 18 is a hopper edepted to receive the, eye.- lets or other parts to be setend deliverthem to the magazine. which latter comprises a j disk-shaped plate-l7. The plate 17 having roadway l 9 depending therefrom is pivotelly l I supported on a stud which projects from the frame of the machine throu h a central The freerend of the up- Lock nuts'lf on the shell 22, the mouth of which is closed by a openmg in the plate. The shell 22 is like l wise rotntehlysu ported on said stud 25 and for this purpose 1&5 an axial sleeve 62 (Fig.

l 3) to receive the stud. The stud 25 has n j head 63 which holds the shell from working oil' the stud. The rim or the shell is idrrne I 1 with teeth ti hthe spaces between the teeth heing suitnhly shaped to receive, each an eyelet. The shell as will next be described has an intermittent rotary motion, and accord ingly any eyelets received into the spaces bel tween the (it will be carried along with l the shell until the opening in the roadway 19 is reached, when one at a time they will drop down said roadway. (Sec big. 2.) words the hopper 18 delivers into a magazine made up or a plate 17 and shell 22, which latter is provided with segregating devices or teeth 64 which act as the shell intermittently rotates to segregate the eyelets and deliver them to the roadway 19. iileans indeperiul ent of the head 63 on stud 2.5 provided for preventing the roadway from working off the stud 25, said means comprising an extension 66 (F 1, 2 and 3) from the roadway, which works under the end of the lug 65 on the machine-frame; the result of the construction being that the roadway can swing freely in the direction of its customary motion to and from the setting devices, but cannot move away from the machine in the direction of the stud 25 and consequently can not work oll' said stud until the roadway has been swung beyond the normal limit of its motion from the setting devices to completely remove its projection 66 from under the lug 65., whereupon it can be removed from the stud 25, as when making repairs or adjustment of the machine.

The intermittently rotary motion of the shell 22 is eflectcd by mech anism comprising a crank 20.0n the right-hand trunnion 60 (Fig; 3), of the upper togglearm 7. Said crank is operatively connected with the shell by means of a connecting rod 23 extending between the crank 20 on the one hand and the periphery of the disk 24 on the other,

rocking of the crankQOEis it swings with the upper toggle-arm 7.

it will henoted from what has been said that the roadway 19 depending from the plate 17 swings on an axis which-is in com men with the axis o'f'rotation of thsshe'll and that this is substantiall through. the center of gravity of the shel or magazine. A spring 7U between the frame and roadway causes the latter normally tooccupy a pr sition in which its delivery end is vertically undor the spindle 12 (compare Fig.3) whereby said spindle on its descent threads through the end eyelet carried by the roadway to delivcr it down into the material to be eysloted. Alter the spindle has impaled the eyelet, the roadway is automatically swung back out oi the path of the set 11 by a roller 2S) (tips. 1, 2 and 3) carried by the plunger 9, whirh roller bears against the cam-edge oi the ramplste 30 on the roadway. Th curve of said ranuplato is surh that the :r does not act to displr e the roadway the descent ol' 'ihruntil in other l'spindle has impaled the eyelet at which time the roller encounters the incline of the cam and forces the roadway out or the path of the descendingset. (See Fig. 2.)

To keep the roadway out of the path of the set, both for the rest of its down motion and its return upward motion, automatic meansis provided to latchlhe rzmdwsy in ils out oi the way position. Said means (5011M prises a latch 31 pivoted to the ironic at 32 and havinga hook end which engages a corresponding catch 3?; on the roadway. when it has been swung out of the path of live srl by the riiller 29'. This lilivll l'llllziillS engaged until the plunger 0 in its up-sirolrv hri-iigs the roller under the lslch, ihcrohy disengaging it and per-milling the roadway to swing hack into its uorn'ial position 'wil h its delivery end under the spindle.

Among the advantages o'l suspmulingthn, roadway so that it swings about an axis which is the same as the axis oi" rotation of the eyelet shell or magazine is that as the roadway shifts at each operation of the machine, it does not displace the magazine and consequently power is saved which" would otherwise be expended in shifting the weight oi. the magazine and its conlrnts. Moreover in addition to econoinizingg power and so making the machine easier running, there is no shaking or rel-king oi" the magazine, also much less noise as compared with construction in which the rondwavpivots about a diii'erent from the axis of rotation of the magazine or shell.

Having described the means 'for 'feedingthe eyelets it will now he convenient to de scribe the means for feeding the other member of the "fastening device, to wit: in'this case the washers. The magazine for washers designated 34 is IIIOLllrlHl on the frame. It has a roadway 35 descending therefrom which. delivers the washers into a stationary funnel tube 86. The contruction of these parts forms no part of my present invention and it will he su'liicient to so v that the washer her; and its roadway :u

the tribe to form a stark therein, the bottom washer resting on a roadway 37'(compare Fig. 4:) next to he (lcsrrilind. This roadway 37 for washers pivolrd at one end to the. frame and extends l'orward under the lower or delivery 0nd of the washer tube 36 to the eyelet setting drvicrs.

illechanism as 'l olloWs provided for feed lug the washers delivered i'l l' l'llim '36 For Ward along the masher roadway 37'to the setting devices, said moi-ha nism comprising a reciproraling sl de BIS working in the slot or guirc of the rmzdway in hack of lhe delivery point oi 1hr washer 'lulw :zo and adopted at each form l rwiprrmilion, llllli is at each lowizrd liarz-wtliizg' dcvic -s o loin nailhr)! oi lhr pile il(liVCl'P(l push the not by the tube 36 forward to asuflicient dis vided with a pin 39 located in the slotted. end

of the elbow lever 40 hilcruined on the l'rame at 41. The horizontal arm of said elbow lever pivotally connects with a vertically reciprocating rod 42 working in sleeves 43 on the frame. The uppeuend of this rod is providcd with a roller 4-4 held in contact with the periphery of the earn-disk l'already de scribed. The means for holding said roller yir-ilding in contact with said disk comprises a spiral spring 45 around the rod and located between a collar 46 above on the rod and sleeve 43 below 'ol' the frame. The result of the construction is that the pulley is driven the cam disk depresses the rod once in each revolution, rocking the elbow lever and moving the slide forward. linmediately al tor, the reverse motion of the parts takes place, since the rojection on the cam disk aving passed, the spring, restores the parts to their former position. One of my present improvements relates to this portion of the machine and consists, inthe specific devices shown, in forming the horizontal arm. of the elbow lever l0 in two parts hinged on each other at 417 to ivot downward, or in the direction of the t irust of the operating rod 42. A catch 48 connects and gives rigidity to the two parts of the horizontal arm for all normal thrusts thereon. That is to say for all thrusts sufficient to push the washers along their roadway, but is not sufficient to withstand an abnormal thrust such as takes )lace in the event that the washers in the roadway should be already full or should become jammed, in. which event the catch yields to I release the two parts of the horizontal arm the elbow lever thereby preventing the rod 'from transmitting its thrust to the washer pitihing device and thereby saving these and related parts of the machine from injury in such a contingency.

The deliveryend of the washer roadwayis provided with a vertical opening somewhat smaller in diameter than the diameter of the waslur so that an annular flange 49 is provided For its support. is concentric with the spear point 13 whereby a washer in the delivery end of the roadway has its lower face r csting oh top of the anvil MS with the s max point projecting centrally through the hole in the washer when the roaday is depressed. The roadway is held normally in elevated position (see Fig. l) by a s Jriug 50 located between it and the frame.

A rociprocatinp presser foot 51 is provided which is adapted to press the material down on the delivery end oi the washer roadway and over the spear point to pierce the nza- Said vertical 0 )ening,

terial with the hole which thereafter to receive the eyelet. T his presser foot is con- 'nected. with the plunger 9 carrying; the topset and spindle to be carried down wit h these parts to]? a portion of their down-str ilm until 0 said toot has pressed the washer roadway into its lmvermost position and has forced the spear )oint tlirough the material gripped between the presser foot and the roadway, at

wh'ch time the downward motion of the prosser foot is arrested, while the plunger, s t and spindle continue on t heirdown strolre, the spindle carrying, an iin aled eyelet (Fig. 6) to the hole in the material by transferring it to the spear point within said hole, said so transfer taking place by the end oi the s indie contacting with the spear point and t ereby becoming teleseoped into its set 11, which thereupon contacting with the top of the eyelet forces said eyelet over the spear Point and down into the hole .in' the material.

Since by the operation of the washer feeding device there will always be a washer at the delivery end of the roadway, and since as already explained said washer at this stage of the setting operation, will be located around the spear point in contact above with the bottom side of the material and below resting on the anvil, it will be seen that the.

above described operation of iorcim the evslet into the hole in the material will force its clenching edge or run through the hole 111 the washer and that said run coming in contact with the topo'i the anvil will be clenched under the washer by the completion of the downstroke of the setagainst the top of the eyelet. Upon the upward stroke due to the release of the toggles of the machine, the plunger, set and spindle rise clear of the work and during the end of their upstroke release the resser-ioot and elevate it also from the wor 4 preparatory to the next operation of the machine.

The inechzmisin for effecting the described interaction between the plunger with its carried parts and the presser-foot, being old so fill y present improvements are con cerncd, need not be described in detail. It will be suflicient to say that said cooperation is effected by connecting the pressei l oot 1'15 with the longer through a cam 52 pivoted at 53 to the ressw-foot rod, which cam has a pin 54 wor ting a cam-slot 55 formed in the plunger. A. pin 56 on the plunger suports the cam when in the position shown in 12s i i 5. When through theintervention of thecam, the danger during the first part cl its do'wn strol ze carries the presser-foot, as described, into contact with the work, the

cam at this noint assumes the vertical posh 12 tion shown in Fig. 7, wherein its endhss come under a ortion 1 of the frame of the n'lachine. Tins holds the presser-foot im" rnovahle in contact with the work, while the plun er-u? is to continue its downward rotate about the axis oi the shell movement independent of the presser-ioot, because the vertical portion oi the cam-slot in the plunger then receives the pin. on the presser-foot coin. Upon the return or up stroke of the plunger the presser-toot cam is rocked out of its vertical. position with con-- sequent release of the presserdoot as soon as the curved portion. of the plunger cam-slot coacts with the pin on the cam. It will be noted (see Fig. 8) tl'iat the opening through the resser-foot large enough to take thrrmgh it without interference the set 11. As soon. as the presser-ioot is released on the rip-stroke, the spring under the washer roadway acts to elevate the latter and thereby li l't the-how eyelcted material 011' the spear point, preparatory to setting the next eyelet.

Referring once more to the broken lever 40 with catch connection 48, it may be stated that it is highly desirable to provide a stop adapted to limit the u ward movement of the horizontal arm. of the ever 40 to the oint' at which thccatch 48 will engage with t e other part of the horizontal arm as same is carried up with the spring-pressed rod 42. For this urpose said stop may consist-of a lug 67 trom the machine frame having a vertical threaded opening through it to receive a screw 69, the free end of which is adapted to engage against a lug 68 from the side of the lever40. In use the screw 69 will be adjusted so thzit it will abut against the lug on the lever 40 when the horizontal arm. of said lever reaches the osition indicated in Fig. 1. A top view of t e described stop devices is-seen in Fig. 4.
